jQuery's ability to load pages seamlessly is unmatched

My website is filled with images, and in order to speed up the loading time, I added a loading screen. Currently, it's a white overlay with the following CSS:

#loader{
    width: 100%;
    height: 100%;
    position: fixed;
    z-index: 9999999999999999;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background: url('loader.gif') 50% 50% no-repeat rgb(255,255,255);
}

Here is the jQuery code I currently have:

$(window).load( function(){

    $("#loader").fadeOut("slow");

});

Right now, the loading screen and the rest of the website load simultaneously, creating a messy look.

Is there a way to ensure that the rest of the page only loads once the loading screen is fully displayed?

Answer №1

After implementing the solution from jQuery callback on image load (even when the image is cached), the code below demonstrates how to handle image loading efficiently:

$(window).load( function(){
    var totalImages = $('img').length, // keep count of total images in the page
        loadedImages = 0; // track images that have loaded

    // listen for the load event on each image just once
    $("img").one("load", function() {
        loadedImages++;  // increment loaded image count
        if (loadedImages == totalImages){
            // all images have loaded, so we can hide the loader
            $("#loader").fadeOut("slow");     
        }
    }).each(function() {
        // check if images have already loaded from cache
        // manually trigger load event for cached images
        if(this.complete) $(this).load();
    });
});

To optimize the loading speed of your website, consider using ajax to load images after the initial page content has loaded. This method can significantly improve the loading time of your website, especially if it contains a large number of images.

Here are some steps to improve your page loading experience:

Start by loading the initial page without showing the loading screen.
Use jQuery to load the loading screen when needed.
Load images dynamically using ajax.
Once the images are successfully loaded, fade out the loading screen.
After that, display the images on the page using the following codes:

#

#loader{
 width: 100%;
 height: 100%;
 position: fixed;
 z-index: 9999999999999999;
 display: none; // initially hidden
 top: 0;
 left: 0;
 right: 0;
 bottom: 0;
 background: url('loader.gif') 50% 50% no-repeat rgb(255,255,255);
}

Jquery:

 $(function(){
     $("#loader").show();

     $.ajax(
      url: "url_to_process_ajax.php",
      type: "GET",
      data: "get=images",  // send image request to server
      success: function(data){
        // handle image processing
        // once done, fade out the loader and show the image area
        $("#loader").fadeOut("slow", function(){
          $("#image_container").show("fast");
        });
      }
     );

});
